Checking the relay supply

Remove the locking relay (2/111).

Measure the voltage between 5 in the relay socket and ground.

The voltmeter should display battery voltage.

HINT: If the value is OK but the fault still remains, connect the contacts to the lock module and link between 3 and 5 in the relay socket to force-feed the lock motor while continuing to test.
